This invention relates to improvements in 'air conditioners and has particular reference to a vdevice wherein air may be effectively cooled through the use of water without'add- 5 ing moisture to the air being conditioned.

A further object is to produce a device which is simple in construction and takes up a minimum amount of space.

A further object is to produce a devicel" which -is relatively quiet in its operation.

A still further object is to produce a device which is economical to manufacture. f

`Other objects and advantages will be apparent during the course of the following delf' scription. .A

In the accompanying drawings forming a i' part of this specification and Ain which like numerals are-employed to designate like parts throughout the same, l

Fig. 1 is a vertical cross section taken on the line 1+1 of Figs.v 2 and 3,'

Fig. 2 is an end elevation looking from the ri ht-hand end of the drawing of Fig. 1,

` ig. 3 is an end view looking'from the left- 2.-. hand end-f Fig. 1, and

f Fig. 4 isan enlarged detail cross sectional view of a spraynozzle. v In conditioning air it is customary to blow a current of air throug a spray ofwater. so as to reduce the temperature of the airk through the evaporating of a certain proportion of water. This results in the-air leaving thedevice with a very heavy moisture content which -is often detrimental to the health of ,the persons breathing this air. Applicant hasv thereforedevised an air cooler wherein the Vevaporation takes placethrough the mixing of-air and water, and this cooling .caused by levaporation, transmits its effect to air which .is kept out of contact with the water. In the accomp-anying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the m1- meral 5 designates a base upon which is mounted an outer shell 6- within which is positioned an innershell 7. The shell 7; is 1spaced from the shell 6 as. illustrated in .Fi land 2. The shell 6 hasa guard 8, while t e shell 7 has a guard 9. A partition 11 extends 5 between the shell 6 and shell 7 and prevents l circulation of air therebetween, except in a denitepath. y l An end plate 12 istted to one end` of the shell 7 and serves to support the ends of pipes 13. These pipes extend parallel to the shell 5` 7 and 'havc their ends bent so as to connect with the shell 7 as indicated at 14. At 16 I have shown a motor having a shaft 17, which n.

is journaled as at 18 in' the plate 12. A fan 19 is secured to the shaft 17 at a point adjao0 cent the guard 9. A fan 21 is also secured to the shaft 17 at a ypoint adjacent the, guard 8.

A water pipe is shown at 22, which has a"suit able'valve 23 and a nozzle 24. The nozzle 24 may be ofv any desired construction, and -is lso arranged thata spray of water issuing therefrom will be encountered by the blades of the fan 19, and blown over the pipes 13 toward Y* the plate 12A.

permit airto'bedrawn in by the fan 19 as well Aas the 'water from the spray draining into a telescoping/or extensible discharge pipe Openings 26,` in the bottom of the casing 7, "to

27, which discharge pipemay lea-d to any suitable outlet so that the moisture laden air and water will be removed from the room. It'will therefore be apparent that the air to be cooled will enter the space A, pass into the' ends 14 of the 'pipes 13 and during the passing throu h these pipes thisairwill be cooled through t e effect of evaporation, will be discharged bythe fan 21 andthe water and air passing over these pipes will be drainedout into the pipes 27 and discharged out of the room while the cool air .will take the path asindicat'ed by ,the arrows, at the extreme left ofthe drawings. n

It will thus be seen that I have f reduced a device which will accomplish a the objects above set forth.

It is to be understood that the form of my invention herewith shown -andldescribed is to be taken as -a preferred example ofthe same and that various changes relative to the material, size, shape ,and arrangement of parts may be resorted to without departingl from the s irit of the'invention or the scope 'of the subJoined claims.l l' Having thus described my invention) I -c aim 10 1. In a device of the character described,

' a pair of spaced shells defining a passagewa for the passage of air therethrough, a sha extending through said shells, fans secure to said shaft and the opposite ends thereof, a plate secured to one of said shells, pipes extending through said plate, whereby air may be drawn through said pipes by one of said fans the other lof said fans forcing air overn sa1d pipes.

2. In a device ofthe character described,

a pair of spaced shells defining a passagef Way for the passage of air therethrough, La shaft extending through said'shells', vfans se- 15 cured to said shaft and the opposite end thereof, a plate secured to one of said shells, pipes extending through said plate, whereby air may be drawn through said pipes by one of said fans, and means for discharging a fiuid l30 ovel` `theexterior of said pipesA through the action of oneof said fans, said last mentioned fan also forcing air over said pipes. 3. In a device of the character descrlbed,

an outer shell having a forwardly formed .lg'guard thereon, an inner shell spaced from said first mentioned shell and having a rearwardly formed guard thereon, said inner l shell havingwa plate securedA to one endthereof, a shaft extending through said plate and ao axially arranged in said inner shell, a pair of fans secured to said shaft at 'points adj acent said guards, and means for rotating said shaft, al nozzle positioned within said 'inner f shell and adapted to conduct a spray of water 85 against one of said fans, and pipes secured to said platev and having their opposite ends curved and connected to said .inner shell at the rear portion forming an air intake. In testimony whereof I aiixmy signature. 4o CLEMENT L. DORLAND.
